Now Software today announced that it has added integration with Apple’s Mac OS X Address Book to Now Up-to-Date & Contact, its popular calendar and contact manager. Address Book integration is available as a free standalone sync application for users of Now Up-to-Date & Contact Version 4.1 and higher. The application lets you synchronize your contact files between Now Contact and Apple’s Address Book. It also allows you to select the direction of import/export, the categories of contacts to be synced, and the categories into which new contacts are placed. These capabilities make it possible for users of Now Up-to-Date & Contact to eliminate multiple contact information entries, and to take advantage of iSync and Bluetooth to transfer data to Bluetooth enabled phones.
